What key tool do law makers use to secure the passage of public works legislation?

Lawmakers often use earmarks as a key tool to secure the passage of public works legislation. Earmarks are specific provisions that allocate funds for particular projects, allowing legislators to direct resources to their constituencies. By including earmarks, lawmakers can garner support from local officials and constituents, making it easier to rally votes for broader legislation. Additionally, they may use negotiations and compromise to align interests among different stakeholders and secure bipartisan support.
